"prodromal phase: symptoms are non-specific but can include: anorexia, diarrhoea, fever, erythema of the skin, nausea, vomiting and headache. This usually appears 1-3 days after exposure. Lymphopenia is an early sign on blood tests."
"latent phase: with an apparent improvement in symptoms and may last hours or weeks."
"Radiation-induced cytotoxicity causes many of the symptoms of the syndrome together with the inflammatory SIRS-like response to the large degree of cell death. More rapidly proliferating tissues (e.g. skin, bone marrow) are the most affected."
"prodromal phase: symptoms are non-specific but can include: anorexia, diarrhoea, fever, erythema of the skin, nausea, vomiting and headache. This usually appears 1-3 days after exposure. Lymphopenia is an early sign on blood tests."
"gastrointestinal symptoms (5-20 Gy): diarrhoea, electrolyte and fluid disturbances, gastrointestinal bleeding and perforation"
"In the haematopoietic syndrome, white blood cells and platelets are lost predisposing to infection and haemorrhage, which are the most common form of death. In the gastrointestinal syndrome damage to the mucosal cells results in diarrhoea, electrolyte and fluid loss and predisposes to bleeding and perforation. Damage to endothelial cells in the brain is thought to lead to vasogenic oedema and potentially neurological symptoms at high enough doses."
"route of exposure (e.g. external irradiation versus ingestion)"
